If that's what you consider intelligent thought, then by all means play Halo. I for one play FPS's when I want to just log on and shoot some people, for games that I have to think about I turn to RPGs. Besides Halo is pretty mediocre as far as the PC FPS market goes, the only reason it's popular is that it dominates the console FPS market which is actually on a whole has been pretty crappy. If halo had been a PC only release it wouldn't have been anywhere near as successful since it doesn't really compare to the PC FPS's.
I played Halo for PC and found nothing amazing about it. Guess that's cause i'm use to PC FPS's. I can see, however, why someone who's only played the console FPS games would find it amazing compared to what they're used to.
